liftingMatrix -- arrange values of lifting function in a matrix

Description

This function was added in version 1.2 of the package Jets.

This function collects the values of the liftingFunction $l_s (j,k)$ and arranges them in an r by c matrix $L_s (j,k)$ with row index $j\geqslant 0$ and column index $k\geqslant 0$.

i1 : liftingMatrix(2,3,5)

o1 = | 1 0 0 0  0  |
     | 0 3 3 1  0  |
     | 0 0 9 18 15 |

              3       5
o1 : Matrix ZZ  <-- ZZ

For uses of the lifting matrix, see Example 4.

Ways to use liftingMatrix:

  • liftingMatrix(ZZ,ZZ,ZZ)
